Time Travel just not possible!

[Themuffinman]

Ok hear is a senario. Lets say time travel is possible. Jack and Jill discovered a way to travel to the future. Jack and jill are both In the same room. jack travels 1 year into the future. Jack would see his basement one year older still made up from the same matter it was made up from a year earlier. Meanwhile Jill is looking at the same basement. Two identical objects can not co exist if they did, they would not be the same.

What is your point? If Jack is now in the future how are the two basements "co-existing"? Suppose Jack's time machine took a year to get him one year in the future. Would your objection still hold?

The quantum world would disagree...

Themuffinman,

Does the room 'travel' with Jack or does the room not travel with Jack and stay with Jill?

[Themuffinman]

Only jack travels through time The basement stays were it is

[turin]

The basement (and observer Jill) only exists for one moment in time?

There is only one basement. Matter is neither created nor destroyed.
